winform 拟态窗口 DialogResult 并传值

打开一个页面，并获取这个页面传回的值

this.DialogResult = DialogResult.OK;

如果点击右上角的X，那么会传回

DialogResult.Cancel

 

 

public partial class passwordcheck : Form
    {
        public passwordcheck()
        {
            InitializeComponent();
        }
        public string _passwork { get; set; }

        private void button1_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(textBox1.Text.Trim()))
            {
                MessageBox.Show("請輸入密碼");
            }
            else
            {
                this.DialogResult = DialogResult.OK;
                _passwork = textBox1.Text.Trim();
                this.Close();
            }
        }
    }

　　

passwordcheck newform = new passwordcheck();
            if (newform.ShowDialog() == DialogResult.OK)
            {
                string pwd = newform._passwork;
            }
